Frequently asked questions
Can period underwear handle a heavy flow?
Yes — Heavy and Overnight styles are designed to absorb several pads' worth. For very heavy days, many women use them as reliable backup with a tampon or cup.
How often should I change on heavy days?
Every few hours, similar to a pad. Keep a spare pair with you in a discreet wash bag.
How do I wash period underwear?
Cold rinse, then a cold machine or hand wash, then air dry. No bleach, no fabric softener, no dryer — that keeps it working for 2+ years.
